Avidemux is available for Linux, BSD, Mac OS X and Microsoft Windows under the GNU GPL license. The program was written from scratch by Mean, but code from other people and projects has been used as well. Patches, translations and even bug reports are always welcome.
Avidemux has built-in subtitle processing, both for Optical Character Recognition (OCR) to soft subtitle formats (VobSub sub, ass and srt) and various hard subtitle VobSub capabilities. While it is primarily a GUI program, Avidemux can also be run from and through the command line (which can also be used for batch processing and debugging).
